In a pilot study, 21 patients underwent transbronchial fine needle aspiration (TBFNA) using a 45 cm-22 gauge needle guided by means of a semi-rigid metal sleeve, which was introduced through a standard rigid bronchoscope. A total of 33 aspirations were performed from main carina (15), paratracheal (five), and lobar carinal (13) foci. Six aspirations yielded malignant cellular samples, 22 aspira...

  Background & Objective: Chronic non healing ulcers or scar undergoing malignant transformation is a rare phenomenon with an estimated incidence of 2%. Though, numerous predisposing factors have been identified, still it is rarely diagnosed and commonly mistaken for a benign condition. The objective of this study was to verify the efficacy of the Fine Needle Aspiration Cytology/ Scrape cytolo...

The cytological features of testicular germ cell tumours were established in smears from 15 freshly resected tumours. These features were applied to the fine needle aspiration cytology diagnosis of metastases in 27 patients referred for chemotherapy. There were 16 positive reports in 32 aspirates of which 13 were taken before chemotherapy and three in patients with residual or new masses after ...

Pre-operative fine-needle aspiration biopsy findings have been compared with those of post-operative histopathology in 146 patients with parotid masses. Post-operative histology showed 124 benign and 22 malignant lesions: pre-operative fine-needle aspiration biopsy correctly identified 118/124 (95.1%) benign masses with an accurate classification of the tumour in 111/118 cases (94%). Fine-needl...

Safe vascular access is a prerequisite for intravenous drug admission. Discrimination between intra- and extravascular needle position is essential for procedure safety. Spectral tissue sensing (STS), based on optical spectroscopy, can provide tissue information directly from the needle tip. The primary objective of the trial was to investigate if STS can reliably discriminate intra-vascular (v...

OBJECTIVE To assess the individual and combined diagnostic accuracy of clinical examination, mammography, and fine needle aspiration biopsy in young women with breast cancer. DESIGN Analysis based on case notes of patients presenting with breast cancer during 1971-89. SETTING A combined breast clinic. PATIENTS Consecutive series of 81 women aged less than 36 with histologically proved bre...

Objective: This study is done to evaluate the diagnostic accuracy of FNA in palpable lesions of head and neck region and find out false positive / negative data to analyze the value and limitations of fine needle aspiration cytology (FNAC) in lesions of head and neck region with Cyto-histopathological correlations. Materials and Methods: From 125 cases, fine needle aspiration smears were taken ...

OBJECTIVE The role of different techniques for mediastinal staging in patients with suspected lung cancer is a subject of debate. The aim of this study was to analyze the diagnostic yield and cost-effectiveness of transbronchial needle aspiration in the mediastinal staging of lung cancer in patients being evaluated in a tertiary hospital. PATIENTS AND METHODS This was a retrospective, observa...

OBJECTIVE To study the costs and effects of incorporating ultrasonography in the triple assessment of palpable breast masses. METHODS A decision analytic model was designed to compare a conventional strategy of performing fine-needle aspiration cytology after clinical examination and mammography, with three different experimental strategies of preceding ultrasonography. Empirical data were us...

OBJECTIVE Computed tomography-guided percutaneous fine needle aspiration biopsy of lung lesions is a simple, safe and reproducible procedure. Currently, it is widely used to diagnose lung lesions. However, different factors can influence the success rates of this procedure. The purpose of this study was to determine the influence of radiological and procedural characteristics in predicting the ...
